OK, so only the middle pair is actually universal, but all three pairs of active-3D TV glasses on my head, and compared below, will work with all 2011/2012 Samsung 3D TVs, as well as with 2012 Panasonic 3D TVs.
So if you have one of those 2011/2012 Samsung or 2012 Panasonic TVs and want to watch 3D sources, you actually, for the first time ever, have a real choice in spectacles. The question then becomes, "Which ones should I buy?"
The short answer is, as always, "What do you want?" If you just want to get 3D capability as cheaply as possible, the Samsungs are a shoo-in. If you're willing to pay more for better comfort and durability, I'd recommend the Panasonics. The more expensive Xpand glasses appeal to a smaller niche than either: people who actually anticipate regularly watching active 3D on multiple TVs (namely, ones incompatible with those Samsung or Panasonic glasses) in addition to their primary 3D television.
The shorter answer is "I like the Panasonics best." If you're into 3D enough to actually be buying 3D glasses for the whole family, it might make sense to grab a pair or two of the Panasonics as primary ("daddy" and/or "mommy") glasses and as many Samsungs as you need for other viewers. For 2012 Panasonic TV owners who just want to dabble in 3D, the $20 Samsungs are as risk-free as you can get.
